i have a loop where a variable value will change in each loop and display those values in each loop. i need to skip the display of the value if the same value repeats from second time
You need to remove the duplicates from the list. Ive chosen StringCollection from the System.Collections.Specialized namespace. But you could use List from System.Collections.Generic
String[] strings = new String[] { "1", "2", "3", "4", "2", "5", "4", "6", "7" };
StringCollection unique = new StringCollection();
foreach (String s in strings)
{
if (!unique.Contains(s))
unique.Add(s);
}
foreach (String s in unique)
{
Console.WriteLine(s);
}
